1 Manifold/header/muffler/tail Pipe problem

Failure Date: 11/11/2020

I took my vehicle to the dealer because the check engine light came on, they had to replace the catalytic converter (by special coverage adjustment 15810), however the technician indicated that I had a cracked exhaust manifold. . . Which was not covered by the special coverage. It is crazy that an exhaust manifold fails! it seems to be a defective part and the technician said it may have been caused by the extra pressure due to the clogged catalytic converter. Gm refused to reinburse this service.

2 Manifold/header/muffler/tail Pipe problem

Failure Date: 12/17/2019

I was driving home from work on hwy 35 outside of dresser, WI and the car dash lights suddenly lit up and the car made a loud rattle and smelled like burning oil. There was no warning. I was 2 miles from home so I came straight home. We checked the oil and added 3 quarts of oil before taking it aproximately 2 miles to our mechanic. They checked the engine and confirmed the rattle was deep in the motor and the motor had blown. After inspection, they found that a small port in the intake manifold was clogged. This caused a pressure build up and the rear seal to blow. We were also then told they had been seeing a lot of this problem in chevy Equinox models. We had to replace the motor for a total cost of $5750. 51.

3 Manifold/header/muffler/tail Pipe problem

Failure Date: 10/25/2019

The vehicle was louding while running, I brought the vehicle to a local trusted mechanic. Upon inspection he determined that the manifold had a large crack in it causing excessive fuel consumption and the engine being loud. In discussing the issue with the mechanic he advised me that he fixed the same exact issue, cracked manifold, with another customers vehicle (same make and model 1 year newer). I called Chevrolet's customer service department and they basically said they are not aware of any issue with the manifold.

4 Manifold/header/muffler/tail Pipe problem

Failure Date: 10/24/2019

After having failing O2 sensors and catalytic converter replaced (under warranty), now the exhaust manifold is cracked and needs to be replaced (not under warranty). The O2 sensors and catalytic converter are attached to the exhaust manifold - could their failures be why there is a crack in the exhaust manifold!?!? my vehicle was making a very loud clattering sound when starting that would go away after a few minutes. I took it into the chevy dealership to have it looked at, they say the exhaust manifold is cracked, and exhaust is leaking out. At times I could smell exhaust from the inside of the vehicle. Only 110,000 miles on the vehicle.

5 Manifold/header/muffler/tail Pipe problem

Failure Date: 03/01/2019

My vehicle has 63,000 miles and when I press the gas peddle and get no response at all. This mostly happens when the vehicle is cold, but it has happened other times as well. I was told to change the intake and exhaust camshafts solenoids, but this did not help. I changed the exhaust manifold, still did not help.

6 Manifold/header/muffler/tail Pipe problem

Failure Date: 03/01/2019

I bought my 2011 Equinox with 45k miles, 1. 5 years ago and have had many problems. Had to change the exhaust manifold, muffler and now I am having power issues. The car will stall when idling and lose power when driving. I had my 3 children in the car and when making a left turn at an intersection I lost all acceleration. Thank god there was not a car coming, because we would have been seriously hurt for it is normally a busy intersection. I still owe a lot of money on the vehicle and I am scared to drive it. This problem occurs often and I was told to change the cam shaft, which I did to no avail.

7 Manifold/header/muffler/tail Pipe problem

Failure Date: 12/27/2018

The engine is a 2. 4l ecotec engine which I've had to have the exhaust manifold repaired twice in basically two years but if you look on-line, this is a very common occurrence with this engine model. It starts off as a check engine fault code, related to exhaust or crankshaft position sensor but the issue tends to be a cracked exhaust manifold. While researching the issue on-line, I see numerous instances of this ecotec 2. 4l engine having this issue-and on different gm models of cars.

8 Manifold/header/muffler/tail Pipe problem

Failure Date: 07/23/2018

My timing chain was making noise. Since other models of the Equinox have a bulletin that covers that repair I drove it into the dealership. On the way there my engine exploded while driving up a hill at 40mph, cracking the engine block and exhaust manifold. Engine needs replacement. Gm will not cover the repair. Issue was reported to gm. It is at the dealership for repair, working off an estimate. I will add the final invoice later.

9 Manifold/header/muffler/tail Pipe problem

Failure Date: 03/15/2018

Wiper blade motor stopped working in a heavy downpour. I was on a road I know so was able to pull off safely. If I didn't know this road I am positive I would have had an accident. The manifold was changed in 2013. Today is March 22, 2018. Last week I had the manifold changed again. Cracked again. There were fumes coming into the passenger area. The car is in the repair garage again because the fumes are even worse. The car has always had a loud ticking sound. It uses a lot of oil. I complained to the dealer before the warranty ran out. They did an oil consumption test and said the oil use was within normal range. How can this be normal range when I put a couple quarts of oil every 200 miles. This car is junk.

10 Manifold/header/muffler/tail Pipe problem

Failure Date: 02/17/2018

I just had to replace the exhaust manifold for the second time in 2 years on my 2011 chevy Equinox due to very large cracks. The car has around 90,000 miles on it and I realoze it's 7 years old, but I tale pretty good care of it and get regular maintence usually at an actual chevy dealership. The first time I expressed my suprise to the mechanic when he yold me there was a very large crack in the exhaust manifold. His response was that chevy Equinoxes are widely known to go through manifolds quickly and frequently, again this was at an actual chevy service station at a chevy dealership. The second time less than 2 years later when the check engine light came on again I took my vehicle to th aaa certified care care center and again same thing, manifold large crack must be replaced and aaa tech told me same story, chevy Equinox manifold are widely known not to last. Only this time in addition to the manifold, the cracked manifold had somehow caused damage to the catalytic converter which is now broken and must be replaced. So my question is, if these are widely known defects among 2010-2011 chevy Equinoxes, why hasnt chevy issued recalls for manifolds and caralytic converters?.

11 Manifold/header/muffler/tail Pipe problem

Failure Date: 09/29/2017

My 2011 Equinox has experienced multiple problems since we purchased it beginning with the oil life monitoring system, which gm acknowledged, through a dangerous failure of the stabilitrak system in 2014 while in motion on multiple occasions (posted to nhsta), resulting in an engine rebuild in 2016, which gm took responsibility for. Unfortunately, the initial problems occurred beyond the lemon car limit in our state and continue today. In September 2017 I brought the vehicle to a chevy dealer after noticing significant exhaust fumes in the cabin particularly while stationary during start up. It was diagnosed with a cracked manifold. The manifold had already been replaced in January of 2016 as part of an engine rebuild at gm's expense. This would therefore be the third manifold in this vehicle in only six years. Both the dealer and I filed with gm customer care to request coverage for the manifold replacement. I have not yet heard back but remain hopeful that gm will once again step up and take responsibility.

12 Manifold/header/muffler/tail Pipe problem

Failure Date: 06/01/2017

The contact owns a 2011 Chevrolet Equinox. While driving with the air conditioning activated, fumes entered the vehicle. Additionally, there was an abnormal knocking noise present. The vehicle was taken to an independent mechanic who diagnosed that the manifold was cracked. The vehicle was repaired. The manufacturer was notified and did not offer assistance. The failure mileage was 67,382.

13 Manifold/header/muffler/tail Pipe problem

Failure Date: 02/13/2017

Exhaust manifold develops chronic crack possibly due to thermal stress gradient near a injection port. Another contributing factor the manifold cracking may be that the engine mount, according to the repair technicians, are prone to quick deterioration than what they consider normal. The engine flops around during torque reactions, putting stress on the connected exhaust system. Besides the cracked manifold, two engine mounts were found in poor condition. This crack does not produce a significant audible exhaust leak sound and therefore goes unnoticed. The exhaust manifold is also hidden from view. The crack is widest when cold, therefore letting the most toxic carbon monoxide concentration enter the vehicle, resulting in carbon monoxide poisoning of the occupants. This is my wife's car. She had been experiencing severe headaches and had made a doctors appoint. I suspected that our wood stove or gas range may have been the culprit, and installed a CO monitor in the kitchen. We figured it was either CO poisoning or a terminal brain tumor. We identified the symptom but not the cause. We thank the NHTSA for their recall of the Equinox fuel pump. It was during this recall that the gm technician identified the cracked exhaust manifold. So the fuel pump recall essentially saved my wife from ongoing low level CO poisoning. Regards.

14 Manifold/header/muffler/tail Pipe problem

Failure Date: 09/15/2016

After coming to a stop at a light, car completely died. Nothing would work. Had to be towed back to dealer. Was sent to a certified gm service center and the timing chain had broke and caused chaos in my engine. They replaced the chain as well as the head and other numerous parts. They also found that my manifold was cracked and had to be replaced. Out quite a bit of money. Now just a few months later, driving down the road and my engine is clicking and ticking and sounds like its going to fall out. I check the oil when I get stopped and my car has no oil in it. No warning lights had come on and my oil level monitoring system still said 38%. It had just reached 3000 miles since my last oil change. Not a happy customer. Tired of dropping money in this vehicle. Also now when I get in my air conditioner make a loud noise until I turn it off and back on.

15 Manifold/header/muffler/tail Pipe problem

Failure Date: 01/31/2015

This car has been burning oil and I have had on three separate occasions in the past few months experienced the car stalling, or near stalling while driving or sitting idling in traffic at traffic light or stop sign. I have complained to the dealer and an independent mechanic both of which told me I hardly had any oil in the engine when checked. (I change my oil as recommended my car is maintained as it should be) my most recent experience was the most dangerous, I remote started my car on 1/31/15, I came outside to get in it and I could smell oil burning, the inside cabin smelled of burning oil/ fire like smell. I witnessed smoke coming from under the car at junction of pipe coming from engine area and muffler. I had my father come and check the car out with engine off my father popped the hood and when pulling the dipstick out to check the oil, the oil shot 2-3 feet in the air onto him and down the driver side wheel well of the car. My father could have been severely burned or had eye damage had in been any closer or standing on side of car when checking. I took the car to the dealership on 2/2/15 I told them what happened they kept the car and checked it, I got a call the same day telling me that the car had to have the pistons, valve cover and time and chain replaced, all covered by my power train warranty (thank god). I feel compelled to tell you this b/c it is very dangerous both for those driving and anyone on the road. I have read numerous complaints about this engine (4cyl) and it seems nothing is being done. I believe Chevrolet should have a massive recall, because obviously something is very wrong! I do believe this has been part of another problem that have complained about early on when I first purchased the car it would, and continues to decelerate while driving, completely on its own and very randomly. This is an obvious safety concern.
